This is the genuine Ametek SBD-4201-G with silver contacts and silver disc.

This solenoid is rated at a full 200 amps continuous on the N.O. (diversion) contacts with a 900 AMP MAKE (engage) and 300 AMP break (disengage) rating.

We have tested this solenoid at more than 440 AMPS of diversion (using approximately a 40-50% duty cycle) with no issues. (Please click here to see our testing results.)

The N.C. contacts are rated at 150 amps continuous, with a 400 amp make and 150 break. (See chart below)

This is TWICE the rated capacity of the copper versions by this manufacture and other vendors compatible copper based products.

Don't be fooled by lower priced copper based models, they handle half the current and can wear out quickly!

CURRENT RATINGS for Ametek Solenoid

Cross reference:

Solenoid Switch Cole Hersee # 24401, 24401BX Prestolite # 15-323

We include a 2.2K resistor and 100uf/100v Capacitor that are put in parallel with the normally closed contacts. This combination called a "Snubber" helps reduce contact arching and can greatly increase the life of the solenoid.

In addition to standard credit card verification procedures which insure the credit card is not stolen, we also verify the computer IP address, phone numbers, etc., to ensure the person placing the order is not doing so for fraudulent purposes. We work with all applicable agencies to prevent and/or report fraudulent or suspicious activity.
